Vampire bats were not studied in their natural habitats until about 1935. During predation, bats first spend a few minutes in the air circling the target prey, eventually landing on the back or neck crest of the animal, and sometimes the ground.

Once the common vampire bat locates a host, such as a sleeping mammal, it lands and approaches it on the ground while on all fours.
